Nothing else than a Touch & Tell with Italian voices stored in the ROM.

The Libro Parlante was distributed already in 1982 by Clementoni. The pictured toy was manufactured late in 1987 and doesn't sport the Clementoni logo. 

LibroParlante_1_PCB.jpg (120018 Byte)This Libro Parlante manufactured in October 1987 by Texas Instruments in the United States includes the Speech-ROM on the main printed circuit board (PCB).

The design is centered around three Integrated Circuits:

CD8012: 4-bit TMS1100 microcontroller with 2k Bytes ROM and 128*4 Bits RAM
TMC0280/CD2802: TMS5110A VSP (Voice Synthesis Processor)
TMC0350/CD62176: VSM (Voice Synthesis Memory) with 128k Bits capacity

The first version of the Libro Parlante makes use of a small module to store the Italian voice.

The next evolution step is the more advanced SuperLibro Parlante.
